45 Claims.

My invention relates to machines for folding the marginal portions of sheet-material With reference to the remainder of the sheet, it being herein disclosed in connection with the folding about the edge of an insole the margin of a covering-sheet which has previously been attached to said insole.

In Letters Patent of the United States No. 2,106,268, Bertrand, January 26, 1938, therev is described and claimed a machine for applying to a ribbed insole a protective covering or socklining. To render this smooth and secure against displacement, the covering, which may be of thin leather, is preferably cemented to the tread-surface of the insole and is also carried over the edge across the feather and against the outside of the rib. To this additional area, the covering is not only adhesively attached and thereby rendered more secure, but when the Welt is applied, the stitching, which passes through both the covering and the insole-rib, Will positively hold said covering against slipping upon the tread-surface of the insole. This machine effects the folding and attaching operations speedily and smoothly, WithA little effort on the part of the operator, and in such a manner that the covering shall extend with substantial uniformity to the edge of the rib, regardless of variations in the Width of the feather. It is an object of the present invention to increase still further the efiiciency and ease of` operation of the patented machine.

In the attainment of the above object, I guard against interference with a member which is movable across the feather of the insole to operate upon the margin of the adhering sheet, by the use of a retaining member, which may be in the form of a finger yieldable transversely of the insole-feather, Which retaining member is arranged to receive engagement of the outer margin of the insole. This not only prevents the feather from rising from the table or support for the insole but also holds the coated margin ofthe sheet, at the side opposite that being operated upon, from premature engagement with the insole. To insure a suitable clearance between a folding and pressing member, which travels with a cutter from the margin of the cover-material across the insole-feather, and the parts upon Which it is to act, this folding and pressing member is mounted upon a support for movement With the cutter and is also movable bodily on said support, so it may be caused to force the material against the insole-feather at the appropriate time in its operating movement. The folding and pressing member is shown as provided With an inclined surface, contacting in its advance with a member Which urges it toward the Work-supporting table,

this occurring against the retracting force of, a`

spring. A novel mounting is provided for a member which acts to press the covering-material against the edge of the insole, together With adjusting means for its actuating spring. To allow the elements Which fold the sheet-material over the feather of the insole and against the rib, to remain at rest at the time of introduction of the Work, so this will be made easy, and thereafter to be started in operation Without effort on the part of the operator, I provide means controlled by the insole for connecting driving means to actuating means for the operating elements. This may be effected by the movable Work-supporting table, which carries the insole against an anvil, this anvil furnishing a portion of cutting mechanism acting upon the margin of the sheet-material. The anvil, in turn, through a carrier upon which it is mounted and which it moves, releases a latch for a connecting member joining the actuating means to the driving means. This action may similarly control movement of the carrier by which the work is advanced for the operations upon it. The carrier is vpreferably retained temporarily in the position to which it is moved by the action of the vvorkV upon the anvil and is released as an incident to the control ofthe machine by the operator at the termination of an operation upon the margin of the sheet. Upon such ending of an operation, the margin-folding and -cutting membersL are located in predetermined positions tomake them ready to act upon the next Work-piece. To facilitate manipulation of the Work and to produce a smoother disposition of the divided marginal portion of the sheet-material formed by the cutting member, the length of feeding steps is made variable by means arranged for actuation by the operator during the operation of the machine. Thus, if when operating upon the more sharply curved peripheral portions these steps are shortened While the cutting rate remains the same, the operator will have moretime to turn the Work, and the` marginal divisions will be narrower and Will lie more smoothly when pressed against the insole-rib. With the Work-supporting and the margin-cutting, -folding and -feeding members, a member cooperates to clamp the work upon the support. This clamping member, in the present invention, is carried by a lever Which is connected for its actuation by a cam device to an oscillatory member for moving the cutting, foldingv and feeding members.

In an application for improvements in Machines for operating upon insoles and methods which may be performedv thereby, led in my name in the United States Patent Oilice on March 10, 1938, and bearing the Serial Number 195,116, there are claims generic to certain features of the present invention.

The work to be performed by this invention will be made clear by consideration of Figs. 17 and 18 of the drawings. In Fig. 17 appears an insole I of the Economy type, which has, in addition to the usual body a, a double-lipped rib b, a reinforcing sheet c of fabric and a sheet s of leather or a leather substitute cemented to the tread or foot-contacting surface of the body. This sheet s covers the forepart of the insole, extending from approximately the breast-line to beyond the toe-end, it being of sufficient size to furnish a margin projecting some distance outside the insole-periphery. The cement employed for attaching the sheet s may be latex or some similar substance which retains its adhesive properties when dry. 'I'he present apparatus completes the application of the cover-sheet s, it folding the extended margin of the sheet up against the edge of the insole, measuring the Width of margin necessary to reach the top of the rib b, cutting it along the line determined by this measurement, at the same time slashing the margin to produce divided portions d, and pressing these firmly against the feather ,f of the insole and the outer face of the rib b. The thuspositioned margin of the sheet s is held in place by the adhesive, the divided portions d accommodating themselves to the peripheral curvature of the insole. This is as shown in Fig. 18.

The illustrated machine includes a column I!) (Fig. 3) upon which are carried, one upon another, a lower casing-section I2, an upper casingsectionY I4 and a cover I6. Depending from the upper section into the lower are opposite brackets I8, I8 (Fig. 1). Upon these brackets and upon the upper section itself, the major portion of the driving and actuating elements of the machine are supported. By removing the securing screws I9, which pass through the cover and upper section and are threaded into the lower, and making a limited number of disconnections, the upper casing-section with the supported elements may be removed as a unit. This gives easy access to all these parts for inspection or repair. The lower section of the casing is adapted to contain oil to lubricate the various connections by splash-effect. Arranged at the front of the casing for vertical oscillation in parallel planes are horizontally extending arms 2E), 2I),piv oted at 2|, 2| upon the casing-section I2 and carrying at their outer extremities a reciprocatoryplunger or holder member 22. The pivotal points are spaced from each other vertically to give a parallel motion, thus maintaining the axis of the member 22 against angular displacement. Upon the -upper extremity of the holder member, a work-supporting table 24 is rotatable upon ball-bearings 26. From the holder depends a rod 28, extending through an opening in a bracket 30 projecting from the casing. Surrounding the rod, and abutting at its upper end against the holder and at its lower against a screw 32 threaded vertically into the under side of the bracket, is a spring 34. The screw 32 has a longitudinal passage to receive the rod. The spring holds the table normally raised by a force dependent upon the adjustment of the screw and to an extent determined by a collar 36 fast upon the rod and contacting with the lower end of the screw. Fulcrumed at the front of the holder 22 is a bell-crank-lever 48, a substantially horizontal arm of which is held normally raised by a tension-spring 42, connecting it to the holder and exerting less force than the tablespring 34. The inner end of the lever-arm is joined by a rod 44 to an unillustrated treadle. An upstanding arm of the lever 40 is arranged for engagement with a rod 46 sliding horizontally in the holder. With the opposite end of the rod contacts the head 48 of a cylindrical slide 50, movable horizontally in a guide-block 52. In ways in the head 48 is held by a slot-andscrew connection 54 for vertical adjustment, the shank of an edge-pressing member 56 extending over the work-supporting surface of the table 24 and having a vertical portion 51, upon which is a work-contacting surface curved outwardly in the direction of work-advance (Figs. 15 and 16). The block 52, with the pressing member, is caused to move vertically, longitudinally of the axis of the table, by the engagement of said table with the edge-pressing member and with an extension 58 from the block which projects under the holder 22. It is guided in this movement by a pin 60 depending from the block and a pin 62 entering an opening in the block. The opening receiving the pin 68 of the guide-block is in a forwardly extending arm 64 of a carrier 66, and the pin 62 rises from said arm. This carrier is arranged to oscillate horizontally, in a direction substantially parallel to the work-supporting surface of the table 24, about a spindle 68 held in the casing-sections I2 and I4'. The carrier may be raised against the expansive force of a spring 'I2 interposed between it and the section I4 and surrounding the spindle. The member 56 is urged normally outward (Fig. 4) by a torsion-spring 'I4 .which surrounds a spindle 'I6 (Fig. 8) rotatable in the carrier-arm 64. One

extremity of the spring is secured to the spindle, while the other bears against the head 48. To vary the force which the spring exerts upon the member 56, it may be tensioned by turning a finger-piece 18 fast upon the spindle. Said spindle is then fixed in the proper position by one of a series of circumferential depressions formed in the hub of the finger-piece and receiving a pin 82 projecting from the carrier-arm.

Normally, the table 24 is elevated by its spring 34, and the member 56 held at its inmost point upon the table by the spring 14, both the table and member being then in their active positions. When the operator wishes to insert an insole-in the machine for the operation upon it, he lowers the rod 44'. This first swings the lever 40 about its fulcrum, forcing its vertical arm against the rod 46 and pressing back the slide 50 against the force of its spring. This continues until the oscillation of the lever is stopped by the engagement with the holder 22, at which time the member 56 has been carried to the periphery of the table. Further downward pull upon the rod 44 is transmitted to the holder, which is lowered against the bracket 30, the spring 34 being compressed. The member 56 descends with the table, the holder pressing against the slide-extension 58 to depress the guide-block 52 upon the carrierarm 64. The operator introduces the insole into the machine from the right, sliding it over the table. Then, the rod 44 is released, permitting the table to be again elevated and the member 56 to be moved inwardly over the upper surface of the table by their springs. At this time, the inner vertical face of the portion 51 contacts with the under side of the marginal portion of the sheet s, turning it up and forcing it against the edge of the insole-body a. In addition to the edge-pressing member 56, the carrier 66 has mounted upon it the following elements, which act upon the work in co-operation with the table (Figs. l1 to 14): An anvil 88; a slashing and trimming knife for the cover-sheet, acting against the anvil, the knife and anvil together furnishing cutting mechanism; a folding and pressing block or finger 92, movable with the knife and acting upon the cover-sheet; a folding and clamping block 94, holding the sheet to the anvil for the cut, and a finger 96, retaining both the insole-feather and the margin of the sheet in position for the folding and cutting operations.

A work-guiding and clamping member 91, between which and the anvil 88 the rib b of the insole I is presented over the table 24, is mounted upon a horizontally extending lever 98, fulcrumed at |00 upon the casing-section I4. As appears in Figs. 2 and 13, the guide 91 is inclined inwardly and forwardly, so it may readily enter and occupy the channel at the inner side of the rib b, and has a corner |02 to lie within the angle of said channel and a surface |04 against which the layer of fabric c may bear. It may be serrated upon its under side at |05, to more effectively retain the work upon the table and is secured to the lever 98 for universal adjustment by intermediate members |06 and |01 and three slot-and-screw connections |08 (Fig. 4).

The anvil 88 is horizontally adjustable in ways upon the lower extremity of a bracket |09, being clamped in position by a screw III] (Figs. 2 and '1). The bracket is adjustable vertically in ways at the outer end of an upper arm II I projecting from the carrier 66. Its movement upon the arm is effected by a screw |I2 threaded into the top of the bracket, with its head turning in a depression in the carrier-arm. To take up lost motion in its support upon the arm and to hold the anvil-bracket in a definite position with relation to the knife, said bracket is urged down by an expansion-spring ||3 interposed between a horizo-ntal extension at the bottom of the bracket and the carrier-arm. The adjusted bracket, with the anvil, is fixed in position by a screw I I4. The anvil has a recess ||5 (Fig. 14) through which a portion of the knife 90 operates. The lower wall ||6 of the recess and the corresponding vertical Wall ||1 below this recess furnish ledgerblades for co-operation with angularly disposed edges of the knife. The outer wall IIB of the anvil, below the recess, is inclined downwardly and inwardly to conform generally to the angle at which the insole-rib is disposed against the guide 91. The inner wall |20 is substantially vertical to support the margin of the sheet s, which is pressed against it by the member 94 during the slashing and trimming operation.

The knife 90 and the folding and pressing block 92 are carried upon a generally vertical bell-Y crank-lever |22 fulcrumed at |24 upon the carrier-arm I II. The knife is adjustable in horizontal ways in the divided end of the lever, it being clamped by a screw |26 (Fig. 14). It is L-shaped, having a horizontal trimming edge I 28 and an adjacent vertical slashing edge |30 cooperating respectively with the anvil-walls IIB and ||1, as previously indicated. 'I'he folding and pressing block 92 has a shank |23 sliding in ways in the forward face of a terminal-portion |2| of the lever |22, to which it is attached by the screw |26. The upward travel of the shank in the ways is limited by the head of a screw I 29 threaded into the terminal-portion, and against this screw-head it is yieldably held by a spring |25 secured to said terminal-portion by a screw |3I (Fig. 13). The block 92 has an outer end wall |32 substantially parallel to the wall |04 of the channel-guide 91. Along the bottom of the wall |32 is a bead or projection |33. Initially, the block is so held by the spring |25 that its lower surface |34 clears the edge of the feather j of an insole resting upon the table 24, as the lever |22 carries the block outwardly, or inwardly with respect to the periphery of the insole. Then, an upwardly and rearwardly inclined surface |35 of the block engages a roll |36 rotatable about a horizontal axis upon a holder |31. The holder is guided for vertical adjustment on a plate |38 and fixed in place by a slot-and-screw connection |40. The plate is held against movement upon the lower portion of the arm of the carrier 66 by a projection I4| (Figs. 7, 8 and 10), secured by screws |42, |42. The inclined surface |35, by its engagement with the roll, cams down the block. This causes the projection |33, passing inwardly well above the edge of the insole, to descend and rub over the margin of the sheet s above the feather, pressing it thereon and into the angle of the outer channel. Finally, the lower surface |34 of the block is forced down upon the entire width of the sheet-margin above the feather to complete its adhesion. In the oscillation of the lever |22, the outer surface of the terminal-portion |2| preferably slides upon the adjacent face of the plate |38. This guides the knife 90, steadying it during its cutting stroke.

Fulcrumed at |43 upon the carrier 66 is a bellcrank-lever |44 (Fig. 5). To a downwardly extending arm of this lever, there is adjustably seknife 90.

cured by a slot-and-screw connection |45 the shank of the folding and clamping block` 94. This block has a vertical, work-engaging face |46 (Fig. 12), which co-operates with the face |20 upon the anvil 88 below the recess i5 'to hold the margin of the sheet s for cutting and thereafter during the feeding of the work, as will later be described. An outwardly extending, generally horizontal, upper arm of the lever |44 lies below a contact-roll |48 upon a projection |50 from the hub of the lever |22. The fulcrum-spindle |43 of the lever |44 is surrounded by and connected to a torsion-spring |52 (Fig. 2), which acts to force the arm of the lever |44 constantly against the roll |48. The face |46 of the clamping block is therefore held initially away from the anvilface |26 by the roll and is permitted to approach said face |`in advance of the knife 99, as the latter is actuated by the lever |22.

The retaining finger 96 is secured by a slotand-screw connection |53 for adjustment longitudinally of an arm |54. This arm is arranged to turn on the carrier 66 about the spindle |24 and is held yieldably in to urge the nger 86 toward i the edge-pressing member 56 by a spring |55,

which joins the arm to the carrier. The movement of the arm under the influence of the spring is limited by a pin |56 projecting from one side of the hub of the arm, this pin lying in a slot in the head of thespindle |24. The lower portion of the finger is bent forwardly to lie close to the side of the anvil 83 (Fig. 2) and normally somewhat outside its wall |29, it being situated inwardly of the insole being operated upon from the At its lower extremity, it is so related to the work-supporting surface of the table 24 that it will admit beneath it the feather of an insole, yet will retain this against substantial upward deection. At its inner vertical edge |51, it restrains the margin of the cover-sheet s from falling upon the featherand adhering irregularly thereto before the associated operating elements lay it over said feather and against the rib b (Figs. il and 12). As such elements act, the

, spring |55 allows the nger to yield, so it travels toward the rib for each cutting and folding stroke and then returns to its initial position.

Considering now the means for imparting to the work-engaging elements their operating movements upon the carrier 66 and to this carrier its oscillation through which the work is fed for the successive operations uponit, these two purposes are respectively effected by actuating mechanisms A and B. Referring particularly to Figs.

- l, 3 and 6, there is journaled transversely in the lower ends of the casing-brackets i8 a crankshaft |58. To this shaft, power is applied through a readily separable connection from a short driving shaft |59 rotatable in a bracket |60 secured to the outside of the casing-section |2. The removal of the shaft |59 prepares for the separation from the machine of the casing-section i4, with the variousA elements which it carries. The shaft |58 rotates continuously during ,the operation of the machine two cranks |6|, |62

within the casing. The crank |6| is joined by a connecting rod |622L to the lower end of a lever |63 fulcrumed upon one of the casing-brackets I8. The upper arm of the lever, together with a link |64, furnishes a vertically extending toggle-lever` which transmits power to a horizontally extending toggle-lever |65, |65. rIhe rear extremity of this toggle |65 is fulcrumed upon a spindle xed across the rear of the casing. The forward end of the toggle |65 is articulated toa substantially vertical armY |66 arranged to turn about a horizontal spindle |61 fixed in the casing-brackets. The arm |66 oscillates uninterruptedly while the shaft |58 is in rotation. Secured to the upper extremity of the arm |66 is a contact-piece |68, which has a downward projection |16. To communicate intermittently the movement of the arm to the operating elements, there is an arm |12 arranged to cscillate about the spindle |61. To an upward and rearward extension |16 of the arm |12 is joined a link |11 for actuating the lever |22 carrying the knife 88 and the folding and pressing block 92. Pivoted upon a spindle |18 fixed in the arm |12 is a connecting arm |80, in the upper rear portion of which is a depression |82 for the reception of the projection |10. Beyond the depression, toward the end of the connecting arm, is a curved surface |83. This surface may be swung'against the projection and ride upon it, until, as the arm |66 oscillates, the depression comes into registration with said projection. Then, when the depression is seated upon the projection as a result of upward movement of the arm |88 under the inuence of a tension-spring |84 joining its outer extremity to the arm-extension |16, the arm |66 will be coupled to and will drive the-arm |12 and the link |11. It will be observed that as the crank |6| turns through 360 in the direction of the arrow in Fig. 3, the straightening of the toggle |65 will give a rest-period, during which occurs the coupling action between the depression and the projection. Then, the toggle is broken upwardly to swing the arm |66 to the right to actuate the knife 88 and block 92, the channel-guide and presser-foot 91 at this time rising under the iniiuence of a cam-slot |86 in the lever 98, this slot receiving a roll |98 surrounding the spindle |18. After this, the toggle is maintained broken to hold the engagement of the elements 88 and 92 with the work, while the feeding movement of the carrier 65 takes place. Then the toggle is again straightened to withdraw the knife and the block, while the cam-slot |86 causes the presser-foot 92 to descend to its work-clamping position. This allows the reverse movement of the carrier in preparation for the succeeding operating cycle and locates the presser-foot in its work-guiding relation.

The above-indicated coupling action by the arm |80 between the arms |66 and |12 is preferably under the control of the work when this is in operating position. Pivoted upon the casingsection |4 is a latch |96, which normally engages at its inner end a short upward extension |92 of the contact-arm |88. This latch holds the arm |80 down, so the depression |82 is spaced from the projection |10, and the driving arm |66 and driven arm |12 are disconnected. The latch |90 is geared at |94 to a short lever |96 fulcrumed at the top of the casing. Upon a forward extension of this lever a block |98 is pivoted, this lying within a horizontal slot in an arm 260 projecting from a rod 202 rising from the carrie-r 66. Considering the release of the latch so the operating elements may be actuated, the lower face of the anvil 88 of the cutting mechanism is normally spaced from the work-supporting surface of the table 24, so there is no lifting effect upon either the anvil or the carrier, to which the former is joined through the bracket |89 and the carrierarm The operator lowers the table by the treadle-connection 44, introduces an insole-blank beneath the wiper and releases the treadle. The spring 34 lifts the table, forcing the blank against the bottom of the anvil, thereby elevating the arm l and the carrier 66 upon its spindle 68.

Consequently, the carrier-arm 200 rises, swinging the lever |96 to lift the latch |90. This frees the connecting arm |80, and, drawn up by the spring |84, its depression |82 engages the projection |16, either directly 01 as a result of the travel of the surface |83 upon the projection. The action of the knife 96 and the folder and presser 92 at once begins, because of power applied by Way of the link |11 from the driving connection thus established. The knife starts its cutting stroke, the block 92 traveling forward with it. As soon as the inclined surface |35 of the block is forced down by the roll |36, the pressure upon the work reacts upwardly to aid in the elevation of the carrier. In its raised operating relation, the carrier is temporarily maintained by a latch 206 (Fig. 4) pivoted upon the casing-section I2 and urged in by a tension-spring 208 joining it to the arm 36. The latch passes beneath a shoulder 2 I0 upon the carrier. An eccentric-mounting 2|2, upon which the latch is pivoted, facilitates the adjustment of its engaging end with relation to the shoulder. When, upon completion of the operation upon the insole-blank, the table 24 is lowered for the removal of the work, a portion of one of the supporting arms 2| strikes a contact-screw 2|6 threaded through a tail 2|8 of the latch 266. The carrier 42 is thereby released, to be returned to its initial position by gravity and by the spring 12.

The carrier 66 is oscillated to feed the work forward for successive cutting and folding operations, while the operating instrumentalities are in engagement with said work. This movement of the carrier is produced by the actuating mechanism B, which is driven from the crank |62. The length of the feeding step is indicated by the angle between the dash-dot lines in Figs. 15 and 16. Since the crank |62 is 90 behind the crank 16|, which has already been considered in connection with the description of the manner of actuating the cutting and folding means, and since this feed-crank acts through similar toggle mechanism, the opposite movements of the carrier to advance work and to return for the succeeding step of feed are performed alternately with the movements of such cutting and folding means. That is, the carrier rests when the cutting and folding elements assume their active positions, the presser-foot being withdrawn; produces feed while the cutting and folding elements are held in engagement with the work; again rests, as the presser-foot acts and the cutting and folding means are withdrawn; and finally returns idly to the initial position with the cutting and folding means. The mechanism B is in most respects the same as the mechanism A, and the parts more exactly corresponding to those of the mechanism A are designated by the same characters and will not be described. From Fig. 1, it will be seen that the latch |96 is common to the two mechanisms, so the elevation of the carrier under the control of the work renders both elfective. When the latch is released, and driving engagement is established for the mechanism B, a link 220 actuated by the horizontal toggle |65 of said mechanism transmits movement to an arm 222 pivoted at 224 upon the casing-section i4 (Fig. 6). Oscillating with and below the arm 222 is an arm 226, which at its under side has a guide-channel to receive a block 228. Turning in a vertical bore in this block is a pin 230, rising from a slide 232 supported for reciprocation along an arm 2,34

projecting from the carrier 66 parallel to the arm 226. As the arm 222 is oscillated by the actuating mechanism B, so too will be the arms 226 and 234, the latter imparting the feeding movement to the carrier and. the operating elements. It will be obvious that the arc through which said operating elements are swung by the carrier, and therefore the length of the feeding steps, will vary according to the position of the slide 232 upon the arm 234 and the corresponding location of the block 228 in the arm 226. To enable the operator to govern the feed, I provide means by which these connecting elements between they two arms may be shifted readily, while the machine is in operation. Fulcrumed about a spindle 240 (Fig. 4) fixed near the bottom of the carrier is a vertically disposed bell-crank-lever 242, an upwardly extending arm of which is united by a link 244 to the slide 232. To an outwardly extending arm of the bell-crank is joined a link 246 arranged for convenient actuation by the operator, as through a treadle. A torsion-spring 248 (Fig. 2), secured at its ends to the spindle 240 and the lever 242,.so holds the connecting elements that the slide and block are normally in proximity to the outer ends of their arms, giving feeding steps of the maximum length. If' there is some condition making desirable a less rapid advance of the work, as at a portion of sharp curvature of an insole, the operator depresses the link 246, carrying the connection between the arms 226 and 234 toward the axis of oscillation of the carrier. The length of the feeding steps is therefore shortened proportionately to the shift of the connection. The extremes of movement of the lever 242 and of the elements which it controls may be adjustably determined by a lateral pin 243 movable with the lever between opposite stop-screws 245, 245. These screws are threaded through a two-armed bracket 241 fixed upon the carrier. This control of the feed is of' especial utility in connection with the smooth laying of the slashed margin of the cover-sheet s against the insolerib b'. As the contour of the rib is more sharply curved, as at the toe, the wider divided portions overlap considerably and tend to full instead of lying flat. By diminishing the length of the feeding steps, while the cutting rate remains the same, the number of slashes made in a unit of length of the rib is increased. With the resulting narrow divisions, the overlap may be reduced to a minimum, and the ideal condition illustrated in Fig. 19 closely approached. The operator also has more time to manipulate the work.

After the machine has been in operation and is stopped by the lowering of the table 24, with the consequent release of the latch 206 and the connecting arms |80 of both actuating mechanisms A and B from the latch |90, the arms |12 should be brought to rest in predetermined angular positions. This is to cause the elements which operate upon the work to be in the correct relation for the initiation of the machine-cycle, when actuating engagement of the connecting arms |80 and the driving varms |66 is re-established. Further, the driven arms |12 should be at their extreme forward positions as the toggles |65 are straightened and are substantially at rest. This relation allows the proper engagement of the depressions |82 with the projections |10. Considering now only the arm |12 of mechanism A, this arm has projecting downwardly and forwardly from it a short extension 250 (Fig. 3), which is provided at its end with a surface of Qllsiderable area. Guided in a bracket 254 secured to the casing-bracket |8 is a plunger 256 provided upon its head with an end-surface arranged for engagement with the end-surface of the lever. The plunger is urged upwardly by an expansion-spring 260 encircling its stem and abutting against a screw 262 threaded into the bracket at the lower end of the plunger-passage. Turning in the bracket is a horizontal spindle 263, and about this spindle is an eccentric-sleeve 264. Clamped upon the sleeve by a screw 265 is a latch 266 having a hooked end urged toward the edge of the head of the plunger 258 by a spring 268 interposed between the bracket and a depending .tail of the latch. The relation between the plunger-head and the angular end of the latch may be adjusted by altering the position of the eccentric-sleeve within the latch. It will be observed-that when the arm |12 is at rest, its position is always'maintained by contact between the surfaces upon the plunger and the armextension 256, caused by the spring 266. As soon as oscillation of the arm |12 begins, one edge of the extension cams down the plunger to allow the hooked end of the latch to pass over the plunger-head. 'This head is now held away from the extension, save for a slight contact at that extreme position of the arm which caused the latching. The latched relation continues during the operation of the machine. Upon depression of the table 24 and the consequent lowering of the latch |96 to engage the arm |86 and disconnect the arm |12 from the driving means, the spindle 263 is'rotated anticlockwise (Fig. 3). 'Ihis is accomplished by a link 214 which'joins the latch |96 to an arm 216 fast upon the spindle. Also secured to the spindle between the latch 266 of mechanism A and the corresponding latch of mechanism B is a bell-crank-lever 218. Upon rotation of the spindle, an upwardly extending arm of this lever presses against a pin 286 projecting from one side of the latch 266. Then, as the force exerted by the plunger 256 against said latch is relieved by the previously mentioned depression of the plunger at one extreme of movement of the lever-extension 258, the latch releases the plunger and resumes its place against the side of the head, ready for the initiation of the next operation. Since the timing of the actuating mechanisms A and Bisdiiferent, the releasing movement which the link 214 imparts to the latch 266 of mechanism A is yieldably transmitted to the latch of mechanism B. A horizontal arm of the bell-'crank-lever 218 is connected by a spring 282 to a horizontally extending arm of a bell-crank-lever 284 arranged to turn upon the spindle 263. The spring holds the forward end of the lever 216 in normal contact with the opposite portion of the lever 284. VAn upwardly extending arm of this lever 284 engages the pin 289 upon the latch 266 for the plunger 256 of mechanism B, these elements corresponding to the like parts of mechanism A. During the earlier portion of this unlatching movement of the lever 218, the latch of mechanism B will resist actuation on account of the pressure of its plunger, and the spring 282 will yield. But when the extension of the lever |12 of mechanism B attains an angle at which the opposite plunger is lowered to the maximum extent, the force applied through the spring is sufijcient to unlatch said opposite plunger which establishes the normal position of its lever |12, as has been explained in connection with the mechanismV A.

The apparatus of my invention operates in the followingV manner. The'driving arms |66 of'both lthe'mechanisms A and B are in constant oscillation under the inuence of the shaft |58, the arms |12 and the work-engaging elements which they actuate being at rest in the positions shown in Figs. 3 and 4 of the drawings. The operator lowers the table 24 through the treadle-connection 44, this simultaneously moving back the edge-passing member 56. An insole I with its adhering sheet s isthen placed upon the table, with the right-hand end of the rib b, as viewed from the toe-extremity, between the face |64 of the channel-guide 91 and the face I |8 of the anvil 88. The rear edge of the margin of the sheet is turned up between the anvil and the retaining finger 96 at the inner side and the edge-pressing member 56, the knife 96 and the blocks 92 and 94 at the outer side. The treadle is then released, and the table allowed to rise, the member 56 moving inwardly over said table. The wall 51 raises the margin of the sheet s and presses it against the edge of the insole-body, at the same time holding the inner face of the rib b` against the guide 91. The elements are now as illustrated in Fig. 11. Since all the elements which operate upon the work are at rest, its introduction into the machine may be effected quickly and accurately. When the feather f of the insole is forced by the ascending table against the bottom of the anvil, it lifts the carrier 66, which is retained in operating position by the latch 266. The carrier swings up the latch |96 to release the arm |66 of the actuating mechanism A. Under the influence of the spring |84, the depression |82 of the arm is caused to seat itself upon the projection |16 of the constantly oscillating driving arm |66, which is thus joined to the arm |12 to be driven. This movement of the arm |12 is effected, with alternate periods of activity and rest, through the double-toggle devices |63, |66 and |65, |65 of mechanism A. The link |11'swings the lower extremity of the lever |22 forward, this carrying with it the knife 90 and the block 92. As the roll |48 of the lever rises, it frees the folding block 94, so this travels in advance of the knife against the margin of the sheet s, carrying this across the insole-feather f and clamping it against the anvil-face |26. 'Ihe finger 96held out close to the edge of the insole against the margin of the sheet by the spring |55,`has during this time performed two functions. Its end has prevented the feather of the insole from curling up to interfere with the movement of the blocks 92 and 94, and it has held the sheet-margin from falling upon the feather and adhering to it before it has been cut and properly folded by the blocks. The finger yields inwardly, so the action of the cutting and folding means is not interfered with. With the margin pressed against the anvil by the block 94, the edge |30 of the knife, co-operating with the vertical edge of the anvil, slashes the margin of the sheet in a direction substantially at right-angles to the feather of the insole to allow turning up the peripheral excess of material without fulling. The edge |28 of the knife, operating across the horizontal anvil-edge, trims off any excess of the margin which would project above the insole-rib b. After these cuts are made, the divided portion d is acted upon by the block 92. Its face |32 engages the portion d at such a distance above the feather f that there is no danger of contact with the edge of said feather. Then, as the inclined surface |35 passes beneath the roll |36, the block descends, wiping the divided margin across the feather. Finally, by the surface |34, it presses the margin firmly down and into the angle of the outer channel by the projection |33, while the end-surface |32 of the block forces the end of the portion d against the outer face of the rib b. The elements in this relation may be seen in Figs. 12 and 13. The latex with which the parts are coated causes the adhesion of the sheet-margin to the insole-edge and the featherand rib-surfaces under the influence of the pressure applied by the member 56 and the block 92. This pressure upon the rib is resisted by the surface |54 of the channel-guide 91.

In connection with the folding block 94, there should be noted its effect in measuring the length of the sheet-portions d as they extend from the edge of the insole-body a. Since the feather Varies in width at different points about the periphery of the insole, and as the cut at the end of each portion d is made by the edge |28 of the knife 9!) before the margin of the sheet s is laid against the outer face of the rib b, the different lengths of the portions d must be determined before the 'cuts are made. The insole is always located in a denite radial position upon the table 24, with respect to the termination of the cutting stroke of the knife 9|), by the channelguide 91 inside the rib and the edge-pressing member 55 and the anvil 88 outside said rib. Outside the wall I 20 of the anvil, the edge of the insole will extend for different distances, depending upon which peripheral portion the operation is being performed. This will be evident from an inspection of Figs. 17 and 18, which show the differences in the width of the feather f, and Figs. 12 and 14, illustrating the relation of the machine elements to the work. As the member 94 folds in the margin of the sheet over the feather, the yielding action furnished by the spring |52 allows the member to lay upon the feather, up to the bottom of the anvil-wall |20, whatever width of sheet-margin may be necessary. This leaves to be added to the length of the sheet-portion d an amount equal to the thickness of the bottom of the anvil, plus the height of the rib. The first of these is constant, and the second, substantially so. A proper vertical location of the knife-edge |28 and its co-operating anvil-edge will, therefore, provide for the correct length of each portion d. As a result of this, when the cut portion is laid in place upon the rib, its end will lie approximately at the top of the rib, regardless of the width of the adjacent portion of the feather.

A covering step has been completed (Fig. 15), during which the channel-guide and presser-foot 91, which have been holding the work upon the table by the engagement of its end |05, is raised to free it for advance in preparation for the next operation. This movement of the element 91 results from the action of the roll |88 of lever |72 upon the cam-slot of the presser-foot-lever 98. A period of rest of the mechanism A now occurs, while the mechanism B is made active by connection between its arms IES and |12 through the arm |80, the last-mentioned arm being released by the latch ISD at the same time as the corresponding arm of mechanism A. But the driving and driven arms of mechanism B are coupled later in the cycle, because of the ninetydegrees separation of the driving cranks ISI and |62 of the respective mechanisms. Through the link 220, the carrier 56 is swung about its spindle to advance a step work grasped by the forming elements, which have cut, measured, folded and pressed the sheet s (Fig. 16). The edge-pressing member 56 travels with these carrier-borne elements because of its mounting upon the carrierarm 64. The table 24 at this time turns freely upon its ball-bearings 26 to lessen the resistance to work-advance. The operator may vary the rate of feed, while the operation is progressing, so as to reduce it, as when rounding the sharply 'curved toe-portion of a blank This is accomplished by shifting the connection between the arms 226 and 234 through depression of the treadle-connection 246. The operator is given more time to make the turn, and the Width of the marginal divisions is simultaneously narrowed, so they may lie more smoothly upon the rib b. Following the action of mechanism B to produce this feed, mechanism A again becomes effective to carry the forming elements away from the work and to lower the channel-guide and presser-foot to hold said work against the table, so reverse movement is prevented. As the last step of the cycle, the carrier returns the forming elements to their initial positions. There are produced in this manner alternate forming and feeding actions, until the opposite end of the breast-line is reached, and the application of the margin of the cover-sheet s to the insole I is completed. At the close of the operation, the table 24 is drawn down by the treadle-connection 44 to facilitate the removal of the completed work. When this happens, engagement of one of the table-supporting arms 2| frees the elevated carrier 66 from the latch 206, and said carrier returns to its initial position. In so doing, it releases, by way of the latch and link 214, the latches 265 of the plungers 256 of mechanisms A and B, which plungers have been held inactive by their respective latches while the arms |12 were in motion. Contact between the faces of the freed plungers and the extensions 25|! of such arms holds the latter in a definite angular relation, ready for coupling at the initiation of the next operation, upon the lowering of the rod 44 by the operator, and with the workengaging elements controlled by the arms in their normal positions.
